The heavier elements on earth were formed

WebThe heavier elements (carbon, oxygen, etc...) are only produced by stars. When our Solar System coalesced, the matter that makes up the planets came from a previous generation of stars. (Meanwhile our Sun is busy making its own slightly-heavier elements, but those aren't ours. Those belong to the next "generation" after our star dies.) WebAug 31, 2024 · This has led mainstream science to accept models that predict heavier elements (> 62 Ni) are produced during the explosions of supernovas. Earth’s elements …

WebHeavier elements are formed in the interior of stars via multiple neutron-capture events. By far the most abundant element in the universe is hydrogen. The fusion of hydrogen nuclei to form helium nuclei is the major process that fuels young stars such as the sun. WebJust four elements make up 91% of the Earth. These are iron (32.1%), oxygen (30.1 %), silicon (15.1%) and magnesium (13.9%). The other elements make up just 8.8%.
